I have bought an "officially supported" Sanyo Innuendo phone. More than half the time it either doesn't work at all, or stops working in the middle of the day. I would not recommend this to anyone. The rest of the apps on this phone seem to work just fine, so I am suspicious of the AccuTracking app itself. Not very helpful given the fact that I am trying to keep my car from getting stolen!

Except for the Android phones, there have been no other comparable phones to iDEN phones in reliability since the iDEN network shutdown in June 2013. Most of the issue was around how the phone handles the background apps. On Sanyo Innuendo, the phone OS manages which app gets the background data access based on the power schema, thus causing uncertainty on the network connection, which impacts how all-time apps like AccuTracking app work.
